Values are mean (SD) unless otherwise indicated.
BMI, body mass index; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity.
Population A: parent population; population B: those without the cardinal respiratory symptoms of breathlessness, cough and wheeze; population C: never‐smokers without the cardinal respiratory symptoms of breathlessness, cough and wheeze; population D: never‐smokers without any respiratory symptoms.
